REALM allows clients the ability to have more than one account using the same email address. This will happen if a different agent sends an invitation to use REALM. By allowing this, REALM ensures that clients can easily collaborate and interact with other agents.
If the client is working with another agent, it is required that they create a distinct username and password that links their account specifically for the agent who sent the invitation. This means that the credentials they use to access their account differ for each agent, ensuring their account remains secure and associated with the correct agent. Clients need to keep track of these new login details so they know which account is associated with the right agent.
